Port Sealing

We perform a variety of Port seals. End-ported bags have tube ports sealed to the end of the bag using either RF Sealing or Thermal Impulse Sealing. All face port seals are done with Heat Impulse Sealing. All Port sealing requires custom sealing tooling.

We perform routine integrity testing of our Port seals. We measure the force necessary to separate the tube or flange port from the film to ensure we achieve complete melting at the port location.
